You can use the MICROAMP HA400 with a desktop pc if you purchase a 3.5mm stereo to 1/4 inch TRS cable. Plug the 3.5mm stereo jack into your computer's headphone jack and the 1/4 inch TRS into the MICROAMP INPUT. If your PC is connected to a audio interface you will need a 1/4 inch to 1/4 inch TRS cable .
